Titanium/Stainless Steel Micro Bottle Opener EDC Mini Lightweight Tool
Even at such a tiny scale however, it is a surprisingly effective bottle opener! At a size smaller than a quarter, it virtually disappears on your keychain when not in use, staying unnoticed until the next time need arises (or you'd like to show it off to your friends, where it is sure to get lots of attention!)
Using a sturdy split-ring for leverage, and placing your thumb on the opposite side of the cap to lift, it makes quick work of bottlecaps, requiring only a single tug to remove a cap. It may not be quite as efficient leverage as a full size opener, but certainly no other bottle opener packs this much prying-punch-per-inch! In fact, it does a better job than many other keychain designs that are many times its size.
